I've been experimenting with socks and sandals. I never wore sandals or flip flops period for most of my life. My wife talked me into the "casual dress?" sandals some time back as summer wear, but I feel like wearing sandals without socks is like sitting on vinyl in shorts in summer; hot, sweaty and uncomfortable. To me more uncomfortable than wearing socks with closed shoes, especially if walking further than house to car. Socks with sandals is just right to me, lighter in summer, heavier in winter. Ultimate breathability and comfort. It's stupid some people consider it a fashion faux pas.
